Build a Blockchain & Cryptocurrency | Full-Stack Edition

Full-stack blockchain+cryptocurrency course! A backend + frontend with Node.js, Express, React, & more!

Code the Future: Build a Full Blockchain and Cryptocurrency From Scratch

This course isn’t just about learning what blockchain is - it’s about building one.

You’ll code a complete, production-style blockchain and cryptocurrency system: a Node backend, a React JS frontend, and a real deployment pipeline - all guided by professional engineering principles.

Whether you’re an individual developer or part of a company designing a technical learning curriculum, this course offers a proven, hands-on way to teach blockchain fundamentals through real full-stack software development.

Why This Course

The blockchain industry has matured - but developer education often hasn’t. Too many tutorials stop at the “theory” stage. This course goes far beyond that.

You’ll build every layer yourself:

• A blockchain with mining, validation, and proof of work

• A cryptocurrency with wallets, signatures, and transaction pools

• A distributed API network using Pub/Sub

• A React JS application that interacts with your blockchain in real time

• A full deployment to a live environment

And you’ll do all of this with clean code, TDD, and professional full-stack structure - the same standards I use in my own work as a software engineer.

What Students Are Saying

“Highly recommendable course for blockchain beginners. You can experience every aspect of blockchain mechanism with hands-on coding projects.”

“As a fellow instructor, this course has given me something to live up to. Just incredible. HIGHLY HIGHLY RECOMMEND.”

“I am a beginner in programming. But I found David to be a prolific teacher. I cannot believe he is releasing this quality material for such an affordable price. Dude thank you so much! You are the best teacher I’ve ever had!”

“The instructor has put a lot of effort to explain every operation in very detail. This course is very helpful for me to understand how React works in web browser. Thank you.”

“Perfect! This course is a must-have for a junior developer.”

Who This Course Is For

• Engineering teams and training programs looking to teach blockchain principles through practical, modern JavaScript development.

• Developers who want to move beyond tutorials and build a complete, functioning blockchain system.

• Intermediate programmers familiar with at least one language who want to learn Node JS, Express, and React in a serious project context.

• Software engineers exploring distributed systems and full-stack architecture.

• Curious learners who want to deeply understand how cryptocurrencies like Bitcoin actually work-by coding one from scratch.

Why Teams Choose This Course

Engineering teams and corporate training programs choose this course because it delivers a comprehensive, project-based learning experience. It delivers a balance of theory, code, and software best practices. It delivers a final deployed product that can be reviewed and demonstrated. And it delivers a repeatable learning path that works for both solo developers and teams.

It’s a single resource that unites backend, frontend, and blockchain principles into one cohesive curriculum.

A Real Learning Journey

Every section is designed to combine deep conceptual understanding with hands-on application:

1. The Blockchain Backend – build blocks, hashing, and validation.

2. Proof of Work & Mining – implement difficulty control and understand the 51% attack.

3. Networking – connect peers, sync chains, and handle live updates with Pub/Sub.

4. Cryptocurrency Features – wallets, signatures, balances, and mining rewards.

5. Frontend Blockchain – a React-based explorer and dashboard.

6. Frontend Cryptocurrency – conduct transactions and mine them from your browser.

7. Deploy to Production – share your project with the world, fully live.

Professional Software Standards

As a practicing full-stack developer, I’ve brought the same level of care to this project that I do to the code I ship every day. You’ll follow modern engineering practices:

• Test-driven development (TDD) with Jest

• Clean code and folder structure used in production Node JS systems

• Express API design for RESTful services

• Reusable React components built with clarity and purpose

• Deployment best practices used by professional engineers

Course Outcomes

By the end of this course, you’ll have your own blockchain and cryptocurrency live online. You'll understand blockchain theory and engineering fundamentals. You'll be able to explain distributed ledgers, proof of work, and cryptography. You'll write full-stack JavaScript confidently with Node and React. And you will build and deploy complex web applications with professional discipline.

What You’ll Build and Learn

• You’ll start with the backend, building a blockchain step by step:

• Design and code blocks, chains, and hash functions

• Implement proof of work and difficulty adjustment

• Add consensus, chain validation, and network synchronization

• Extend the system into a cryptocurrency with real wallet addresses and transactions

• Use Pub/Sub to power a peer-to-peer blockchain network

• Then, you’ll move to the frontend, where you’ll:

• Build a React JS application and frontend to visualize the blockchain, transactions, and balances

• Create a user-friendly wallet dashboard

• Mine transactions and interact with your network in real time

• Finally, you’ll deploy your blockchain so anyone in the world can access and use it.

Why Learn From Me

I’m a full-stack software engineer, and I’ve released more than 17 courses on software development, taken by over 320,000 students worldwide. My mission is to help developers learn modern technology in a structured, motivating, and professional way.

In this course, I’ve brought together my background in software engineering and education to give you the kind of hands-on, conceptual, and complete learning experience that’s rare in online training.

Your Blockchain Journey Starts Here

By the end of this course, you won’t just understand blockchain - you’ll have built one. You’ll have a deployed cryptocurrency system that demonstrates the concepts powering real-world decentralized technologies.

If you’re curating content for your engineering team or investing in your own technical growth, this is a flagship full-stack course built for lasting impact.
